DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0027] like Figures 1-11As shown, the utility model proposes a quick-detachable foldable inflatable boat stern wheel bracket mechanism, which includes a hanging plate 1, which is installed on the stern of the inflatable boat by a plurality of bolts, a first bolt 10 is provided on the upper side of the hanging plate 1, and a hanging groove 11 is provided on the lower side of the same side, a U-shaped support plate 2 is installed on the hanging groove 11, a fixing hole 20 is provided in the U-shaped support plate 2 at a position corresponding to the first bolt 10, the first bolt 10 is inserted into the fixing hole 20, and a locking nut 3 is threadedly installed on the first bolt 10, and a grab 30 is provided on the outer side of the locking nut 3, and the locking nut 3 is against the back of the U-shaped support plate 2, a hanging rod 21 is provided between the two side walls of the U-shaped support plate 2, a rotating shaft 23 is provided below the hanging rod 21, a support rod 4 is movably installed on the rotating shaft 23, and a wheel 5 is provided on one side of the bottom of the support rod 4; limited slots 22 are symmetrically provided on the bottom of the two side walls of the U-shaped support plate 2;

[0028] A first movable groove 40 is symmetrically formed on the front and rear side walls of the support rod 4, and a second movable groove 44 is formed on the right side wall of the support rod 4. A sliding pin 41 is movably installed in the first movable groove 40, and a clamping plate 42 is movably provided on the sliding pin 41. The end of the clamping plate 42 away from the sliding pin 41 is arranged in the second movable groove 44. The sliding pin 41 is connected to the rotating shaft 23 by a tension spring 43, and the tension spring 43 is located on one side of the clamping plate 42 and is located in the support rod 4;

[0029] A fixing hole 13 is provided on the hanging plate 1, which is located below the first bolt 10. A fixing hole 3 24 is provided on the U-shaped support plate 2 at a position corresponding to the fixing hole 13. A second bolt 12 is passed between the fixing hole 13 and the fixing hole 3 24, and the second bolt 12 is fixed to the rubber boat.

[0030] When in use, first, the two hanging plates 1 need to be fixed to the tail of the rubber boat in a symmetrical manner by using several bolts. When moving the rubber boat for shipping, the two sets of U-shaped support plates 2 equipped with support rods 4 need to be installed on the hanging plates 1: first, align the fixing hole 20 of the U-shaped support plate 2 with the first bolt 10 and insert it, then put the locking nut 3 on the first bolt 10, hold the handle 30 and rotate it, drive the locking nut 3 to be screwed onto the first bolt 10, so that the locking nut 3 can fix the U-shaped support plate 2, then pass the second bolt 12 through the fixing hole 13 and the fixing hole 3, and fix it to the rubber boat. At this point, the installation of the two sets of support rods 4 is successfully completed;

[0031] Then manually press the two support rods 4, and the support rods 4 will rotate around the rotating shaft 23 until the support rods 4 and the U-shaped support plate 2 are parallel to each other. The sliding pin 41 is driven by the tension spring 43 to be clamped into the limiting groove 22, thereby fixing and limiting the support rods 4. At this time, the rubber boat can be shipped using a trailer;

[0032] When arriving at the storage location or the riverside, it is necessary to manually pull down the sliding pin 41 so that the sliding pin 41 moves downward and out of the limit slot 22. While moving out, manually swing the support rod 4 upward to bend it. When it is bent to a suitable angle, the card plate 42 can be clamped onto the hanging rod 21 for fixation.

[0033] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
